Goblin Build 133 - Tor transport (replaces the Nym mixnet)

Browse Source 
The wallet's private transport moves from the Nym mixnet to embedded Tor
(arti, copied from GRIM's engine): it dials the relay's pinned .onion, so
the relay never learns your IP, while the relay + NIP-59 gift-wrap hide the
rest - content, sender, and (via a relay-side randomized release) timing.
The Grin node stays on the clear internet as before.

Why leave the mixnet: the Nym free-tier bandwidth this depended on is being
removed upstream (the grant expires at UTC midnight; the paid path requires
holding NYM tokens), so a payments wallet can't stand on it. Tor is
unmetered, embedded in-process on mobile, faster where users wait, and
lighter on the battery.

Preserved intact: the confirm-before-sent guard, relay-gated readiness, and
the lazy warm-on-activity node polling. src/nym/ is feature-gated off (arti
and nym-sdk can't share one binary); full removal is a follow-up.
